To all "whom it may concern: I

Be it known that I, Josnrn L. Roor, a citizen of the United States, residing at Louisville, in the county of Jefferson and State of Kentucky, have invented certain new and useful Improvements in Moving- Picture Cameras and Projecting Devices, of which the following is a specification.

My invention relates to moving picture devices and particularly to cameras adapted for taking a large number of exposures in rapid succession.

More specifically my invention relatesto a camera of the class mentioned which may be also used as a projecting device.

The object of my invention is to provide 1 a camera for the purpose stated which shall be of such small dimensions and of such simple operation that it shall constitute a hand camera and be operated with the same facility as the ordinary kodak.

A further object of my invention is to provide a camera of the class under consideration equipped with a spring motor for operating the same and also with means for manually operating the device, and of such construction that said means may be used interchangeably at the will of the operator without adjustment of any of the parts and without interfering one with the other.

My invention has as a further object to provide improved film and shutter actuating mechanism. I

A further object of my invention is to provide a camera of the class mentioned which may be readily and quickly adjusted or arranged to constitute a projecting apparatus.

Other objects will appear hereinafter.

Vith these objects in view my invention consists generally in the camera and projecting device, and the various details of construction and arrangements ofv parts hereinafter fully described and particularly pointed out in the claims.

My invention will be more readily understood by reference to the accompanying drawings, forming a part ofthis specification and in which Figure 1 is a vertical longitudinal section through a device embodying my invention in its preferred form, the same being taken substantially on the line w'w of Fig. 2, Fig. 2 1s a horizontal section on the line g y of Fig. 1, Fig. 3 is a similar view taken on the line zz of Fig. 1, Fig. 4 is a detail section of the upper portion of the film feeding device and taken substantially on the line ww of Fig. 2, Fig. 5 is a detail view of a portion of the driving mechanism, Fi 6 is a vertical transverse section on the ine o-o of Fig. 1, Fig. 7 is a perspective view illustrating the film moving and shutter actuating mechanism, Fig. 8 is a detail view illustrating a form of light emitting device adapted to be arranged u on the camera when the same is to be use as a projecting device, and Fig. 9 is a detail sectional view on substantially the line TT of Fig. 3.

Referring now to the drawings 1 indicates a light tight camera box formed of two telescopic sections. the front 2, sides 3, top 4: and bottom 5. The other section comprises a back 6, a-top portion 7 and bottom portion 8, which fit against the inner faces of the top and bottom members 4 and 5 respectively and side members 9 which fit snugly against the inner faces ofthe sides 3. To secure the sections together, hooks 10 are provided on the sides 3 which engage eyes 11 on the back 6.

12 indicates a handle provided, preferably on the back, for carrying the device; and secured in the front 2 is a lens barrel 13. The back section of the box is provided with a horizontal partition 14 that divides the box into an upper mechanism chamber 15 and a lower chamber 16 to receive the exposed film. The partition 14 is secured to the back 6 and sides 9 of the rear section in a light tight manner and the forward edge rests upon a strip 17 fixed to the front 2, by which arrangement light is prevented from enteringthe chamber 16.

18 indicates a bushing which may be provided in the bottom of the device to receive the tripod screw.

A view finder is provided in the upper forward portion of the box. This comprises a lens 19 fixed in the front 2, a reflector 20 secured to the top 7 of the back section One section comprises and a lens or v ound glass 21 arranged above the same either in the member 4 or 7 as preferred, said members being provided with registering apertures 22 directly above the reflector 20. I prefer to arrange the poured to the front 2 above the lens barrel 13 is a horizontal member 25 that abuts the plate 24 when the box sections are telescoped. By this arrangement light is excluded from the upper forward portion of the box, and if preferred, a plate 26 may be arranged.

horizontally in the upper portionof the frame 23, extending rearwardl from the plate 24 toinsure perfect excluslon of light from the film as'will appear more clearly hereinafteri 27 indicates a cylindrical box containing the unexposed film, which box is removably arranged in the upper portion of the camera box 1 above the partitions 25 and 26. The film 28 passes from the box 27 to the feed rollers 29 and 30, the roller 29 being mounted in fixed bearings and the roller 30 upon a spring pressed spindle 31 to facilitate arranging the film between them.

32 indicates a pivoted arm upon which the V spindle 31 is mounted and 33 a spring bearing upon the same for holding the roller 30 in yielding engagement with the roller 29. The roller 29-.is provided with the usual projections or pins 34 for engagement with the apertures 35 in the film and the roller 30 with the peripheral grooves 36 to accommodate the same.

The portion of the device just described is arranged entirely above the horizontal partitions 25 and 26 sothat there is no danger of the film beinglight struck as it is fed from the box 27.

Secured to the front-of the plate 24 is a channel member 37 extending from a point above the partition 25 to the partition 14 and forming with the plate 24 a passage way of sufficient cross section to accommodate the film and constituting a guide for the same from the feed rollers 29 and 30 to the com.- partment 16. The lower end of the member 37 is flared as at 38, and an aperture 39 is formed in the partition 14 directly beneath said flared end. To prevent the possibility of light entering the compartment 16 through the aperture 39 felt strips 40 are provided which impinge against the sides of is provided with vertically disposed lateral base flanges 43 arranged in guides 44 formed f by turning back a portion of the base flanges 45 of themember 37. The rollers 29 and 30, 1 that .feed, the film continuously from the b' ox 27 and mechanism, to, be described here- J inafter; for feeding the film intermittently past the aperture 41, together with the shut ..ter,' are operated simultaneously from one 46 indicates the main shaft rotatably mounted in thelower portion of the frame 23 and provided at one end with -a sprocket gear 46- connected by achain 47 to a similar gear 48 on the spindle of the roller 29. The opposite end of the shaft46 is provided with an-eccentric 49 which engages in the slotted arm 50 of a lever 51 pivotally mounted as at 52 upon the side of the frame 23'. The opposite arm 53 of said lever is connected by a link 54 to the shutter 42. It is obvious that as the shaft 46 rotates in the direction of the arrow a, the eccentric 49 will operate the lever 51 to raise and lower the shutter. The

shaft 46 is provided intermediate its ends with a crank 56 to which are connected a pair of rods or fingers 57 the ends of which are adapted to engage in the perforations 35 of the film and move the-film intermittently through the channel member 37 .3 The fingers fingers 57 when they are projected forwardly into engagement with the film. The operation of this portion of the device will be obvious by referring to Figs. 1, 6 and 7.

The shaft 46 may be driven either manually or by means of a spring motor. Fixed to the shaft 46 is a pinion 61 meshing with a gear 62 fixed to an arbor 63 mounted in the frame 23. One end of the arbor 63 extends into a small cylindrical housing 64 fixed to the inner face of the right hand Wall 9 of the back section and is squared as at 65 to receive a crank 66 by means of which the device may be operated manually. The end of the arbor 63 terminates short of the plane of the outer face of the wall 9 so as not to interfere with the removal of the back section from the front section of the box 1. A felt disk 67 is preferably arranged in the bottom of the housing 64, closely surrounding the arbor 63 to prevent light from entering around the arbor. By referring to Fig. 9 it .will be seen the frame and provided with a spring 70 for driving the same. Loosely mounted on the arbor 69 is a gear 71 meshing with a pinion 7 2 fixed to a shaft 72. The shaft 72 also carries a pinion 7 2" which meshes with a gear 62. A ratchet wheel 73 is fixed to the arbor 69 and cooperates with a pawl 74 on the gear 71 in the usual manner to permit winding of the spring and driving of the gear 71 in one direction only. 'The end of'the arbor 69 extends into a housing 64 similar in every respect to the housing 64 and has its end squared to receive a crank 75 for winding the; spring 70. 76 indicates a pawl adapted to engage the teeth on the pinion 72 to act as a stop for the motor driven gearing. One end of the pawl is connected by a rod 77 to a push button 78 arranged in a depression 79 formed in the top of the box 1. When the spring motor is wound it is but necessary to press the button 78 to start the device in operation and releasing said button will immediately stop the device, the spring 80 being provided for returning the parts to normal position.

In order that the arbor. 63 may be operated'independently of the motor driven arbor, the pinion72 is loosely mounted on the'shaft 72 and is connected by a pawl 81 to a ratchet wheel 82 fixed to said shaft. When the pawl 76 engages the pinion 72,

the shaft 72 is held against movement, but

the arbor 63 is free to turn in operative direction owing to the ratchet and pawl connection between the ratchet 82 and shaft 72. It will thus be seen that the manual and motor operating means may be used independently of each other without the necessity of'adjustment or changing any of the parts. To control the speed of the mechanism when the spring motor is used a governor 83 is provided on the shaft 72' equipped with a friction disk 84: which, when the maximum speed is reached engages arm 85 adjustably mounted in the side of the frame 2 v The device above described forms a complete and compact moving picture camera which may be made of such small dimen-' era. When used asa projectingv device the plug 89 is removed and a cylindric'alshell .90 inserted in place of the same. The shell 90 is threaded at its inner open end as atof two parts detachably connected at 94 to give access to the light 93. The bushing 87 is provided with an outwardly extending peripheral" flange 95 and an inwardly extending peripheral flange 96, the latter forming a stop for the plug 89 or shell 90 and the two flanges serving to exclude light when the plug 89 is in position. It should be notedthat the operative mechanism is arranged entirely below the lens barrel 13 and shell 90 with the exception of the feed rollers 29 and 30 so that thereis nothing to interfere to the free'passage of the light from said shell to the barrel 13.
